Return style fuel system
Return style fuel system What all is invloved in this... I have all the parts.. Regulator/Filter/Lines/Rails ect...
Just wondering if there is a write up on how to do it.. The front part seems simple enough but what about the tank area.. How do you connect everyting up back there..

I am going to be doing one soon, parts on order. Bulkheadfitting in the bottom of the tank, should just drill a hole put the fitting in and use the proper sealant around it, mount pump below that and close as possible...return line im not sure, ill look at pictures but i assume it goes in the top of the tank at the sending unit...
Im looking for a how the guys are doing it thats keeping stock setup as far as the fuel pump but running braided line to the front.
I suppose you just bypass the original filter and then connect to the bucket using hose clamps?
If I had my car here I would take a look under there and see how everything was routed..

I'm thinking something could be done with the existing hard lines in the back...it tees off right before the fuel filter to send excess fuel back to the tank, so that is the return. You could eliminate the tee, flare the hard line right there (although I don't know its diameter, so I'm not sure what size AN fitting would fit there - probably a -6 or so), and attach the braided line and run it to the front with a fuel filter somewhere in between. For the return, I was thinking you could use the existing supply hard line that runs to the front, only send the fuel the other way. Going back towards the back, I guess you could just use a couple more flares and some more braided line and AN fittings to bridge the gap.
Unfortunately, I don't know enough about fuel systems to know if this would work or not. I'm also not sure what the fuel regulator in the tank looks like or how to bypass/remove it.

That sounds like it would work.. I didnt know what it looked like around the filter... Ill have to take a look at it when I get home.. I know a lot of people use the stock line for a return.. Thats what I was planning on doing...
The big unknown for me is the impact of taking the stock regulator out of the tank...I'm not sure if the venturi-effect in the stock bucket would still work or not. Anyone have a diagram of where the stock regulator is?

The regulator isn't in the tank, its that T-fitting you're talking about.
I plan to do as described above and drill a hole in the bottom of my tank and use a bulkhead fitting to a pair of Walbro in-lines (getting a good deal on them, and they'll work for what I need for now), and then running an 8AN line up to my engine bay to split into 6ANs to feed my (aftermarket) fuel rails.
As of now, I then plan on using the stock feed line as the return line (I have a 6AN fitting on the stock line right now anyways). I'll be running an Aeromotive 13109 regulator after the fuel rails.
I'm not sure if I'm going to let the fuel drain all the way back through that line or if I'm going to splice it into the actual return line on the sender where the factory regulator was...or maybe even leave the entire stock system alone and just add a 6AN return line and leave the factory setup there as well, I haven't decided exactly yet.

The T-fitting isn't the regulator, it allows the excess fuel to be plumbed back into the bucket. The regulator sits just under the fitting where the return line connects to the bucket assembly.
